In 33 normal subjects aged between 15 and 60 years, the cortical somatosensory evoked potentials (SEP) recorded above the mastoid process, HWK2, LWK1, and the nerve action potential above the poplitea were examined following single stimulation of the tibial nerve at the medial malleolus. There is a correlation between size and N1, P1 latencies of the cortical SEP, but no relationship was found between age and N1, P1 latencies. The spinal conduction velocity determined as the difference between HWK2 and LWK1 did not show any correlation with age. The double stimuli examination showed a rise in the N1, P1 latencies within the relative refractory period on shortening of the interstimulus time. The cerebral relative and absolute refractory times were higher than those of the median nerve.
在33名年龄在15至60岁之间的正常受试者中，在内踝处单次刺激胫神经后，检测了乳突上方记录的皮质体感诱发电位（SEP）、HWK2、LWK1以及腘窝上方的神经动作电位。皮质SEP的波幅与N1、P1潜伏期之间存在相关性，但未发现年龄与N1、P1潜伏期之间存在关联。将HWK2与LWK1的差值确定为脊髓传导速度，其与年龄无任何相关性。双刺激检查显示，在相对不应期内，随着刺激间隔时间缩短，N1、P1潜伏期延长。大脑的相对和绝对不应期比正中神经的要长。
